Can not invite H.323 terminals from on the H.320 terminal over ISDN??

I just set up the IP/VC environment using 3510 MCU, 3525 Gateway and embedded Gatekeeper on 3525.

I could not invite two H.323 terminals to join a conference on the Polycom endpoint over ISDN using 611234**2021**2041 string, the calll alway was forwarded to the defauld extension that is configured on the Gateway. I do believe the VC has been initiated successfully since I could see this conference through MCU web admin page, but no any participant. Then I could invite the H.323 terminal from the admin web page successfully. So I think there is no problem with the communication between the all IP/VC components, it looks like that the invite code "**" is not accepted by MCU or Polycom unit is failed to send the "**" out.

Did anyone have the same experience before and how to address this problem?

Thanks in advance

How many BRI lines do you have ? if you have only one only have 1 BRI line, you can only invite only one H.323 endpoint into a 128k MCU conference.

If I understand your question properly, you are trying to invite an ISDN only connected endpoint by using the IP "invite" dialsting on an H.323 into a multipoint conference on the Polycom. If I'm misreading this, please correct. If this is the case, this is not possible to do. ISDN connected endpoints via a GW need to be dialed using the prefix and full e.164 dial string.
